I2C Error while back from OFF mode

Dear all

       I have done some experiment on my OMAP4430 board. What I needed is to ensure that all the gpio entry the target status as I configured. 

     But when back from OFF mode, OMAP4430 I2C controller stops working even all register settings are restored. The log shown "i2c error". 
     
    Does there exist any workaround with this problem. The branch I used is "4AJ.2.5p2".

       Thanks in advance!

    Hello Jacob,

    Have you checked if all I2C clock settings (that is PRCM configurations for I2C) are ok ?


    What is the platform you are using (?) Blaze or Blaze Tablet? Or is it custom OMAP4430 board?

    Can you provide the steps to reproduce the problem? Also can you send the logcat output, as it may give some additional information?

    Best Regards,

    Yordan
